in the position they assume when the valve is in place the at Spring 23 is povded Open. It will thus be seen that both the sleeve and the Figure 3 represents a pespectve View of the shaft through their connections and relations are element in which the key UlJeTated member S capable of a partial rotary movement, and that ing fOr the Valve Operating means. which opening is of suiiicient size to allow the Figure 4 represents a sectional view taken on proper movement of the shaft to project and line 4 4 of Figure 1. withdraw the latch end 27, from the recess or Figure 5 represents a sectional view taken on socket 28, and this particular feature is one of the -55 line 5-5of Figure 4, i. most important and novel of my invention, Y V110 The purpose of arm 26 entering into the valve block is to retain butterfly valve in locked position, even though the carburetor being removed the valve cannot be forced open from the underneath or carburetor side.

From the construction described it will be apparent that the buttery valve is mounted on the shaft and is rotated by the movement of said shaft into locked and closed position, and is shown in Figures 5, 6 and 7. The wall of the valve block is provided with a pair of openings 29, which lead to the outer air and which, when the valve is fully open, will allow a small amount of air to enter into block positively disrupting the gasoline mixture from carburetor. This is found absolutely necessary under this type of locking conditions to effect the absolute positiveness of a device of this kind.

These openings or vents are covered and uncovered by the shutter device 30, on the extended end of shaft 11, as shown clearly in Figures 4, 5, 6 and 7, which forms a most scientific as well as vmechanical feature of my invention.

To the dash or instrument board is rigidly and reliably secured by means of the lug 31, and lock bolt fastening 32, the tubular member 33, to the lower end of which is fitted the cap 34, formed with an opening 35, and tted in this cap opening and the opening 36, of the ring 37, secured by fastening 38, are the ends of the protecting covering or tube 39, and within this tube and passing throughout its length is the torsional cable or connection 40, and one end of this cable, or, rather, its upper end, is secured to the cylindrical head 41, while the other or lower end 42 is secured to the upper end 43 of the ferrule or cap, and thus movement of the said head 41 and ferrule 15 is effected through rotation of said cable, as Will presently appear.

The tubular head 41, adapted to turn in the guide lower portion 44, of the sleeve member 45, and is formed on the worm or spiral stub 46 which is enclosed by the tube 47, formed with the lip 48, which fits into said worm groove, and the tube is formed on the rotatable key operated member 49, which is moved in and out by movement of the key, and such movement naturally releases lock plunger, then impressed spring pushing lock forward gives the spiral or worm a turn which imparts a rotary movement to the torsional cable which moves the valve to the desired position.

The key operated member is guided in the sleeve by means of the pin 51 and slot 51', in the sleeve and the sleeve is also provided with a series of graduated openings 52, which receive the stud 53, on the member and thus holds the member at different points to open the valve to varying degrees or to entirely close and lock the valve according to requirements.

The key operated member is held to its proper position by the stud 53 and is actuated to its unlocked position by the expansion of coiled spring 54. The ferrule 15 is also retained in proper relation to other parts by means of the coiled spring 55.

From the foregoing description taken in connection with the drawings the operation of my locking mechanism will be readily understood and its many important advantages will be fully appreciated. It will be noted through the action of the key operating member on the dash-board that the valve may be operated and controlled gradually, allowing some power to escape into cylinders that the car may be moved under garagerequirements, or that valve can be fully closed and absolutely locked against theft.

It will also be noted that the Valve may be entirely closed, and when in locked position in the event of the cable connection being cut the ferrule and connected parts operate to lock the valve in shut position.

It will be noted that if the cable or torsional connection is forcibly severed or broken away the ferrule and connected parts are constructed so that the valve will always remain in locked position.

It will be noted that my locking mechanism can be readily installed in motor cars in general use at a comparatively low cost, or as a replacement lock on all types of cars, either now or at time of their manufacture, and that the locking mechanism will commend itself as useful, efcient and practical from every point of view.

It will be noted that the butteriiy valve and the means for locking the valve in the mounting are operated from the dash board and through the operation and control of the key operated mechanism and thus a co-action or co-cperation of the said mechanisms is provided, which is a most important feature of this invention.
